Question
Why doesn't my license work?
Summary
Use list below to troubleshoot license problems.
Description
There are many potential reasons why a license file may not work. Below is a checklist:
Are you logging on to the computer remotely?
By default, STK licenses are only valid if you are at the machine on which it is installed. If you log on remotely (e.g., Remote Desktop), STK will indicate that you do not have a valid license file. If you need to access STK from a remote machine, please contact AGI technical support for assistance.
Is your license in the correct directory?
Ensure the file is located in:
| Version | Default Path |
| STK4 (PC) | C:\Program Files\AGI\stk\4.x\bin4.x\LicenseData |
| STK4 (Unix) | /usr/agi/LicenseData |
| STK5-6 | C:\Program Files\AGI\STK_Version\bin\LicenseData |
| STK7-8* | C:\Documents and Settings\All Users\Application Data\AGI\LicenseData |
*STK7-8 lets the user specify additional license locations. To do this go to the Start Menu under Programs - AGI Support Tools and click License Manager
Did the license get modified or renamed in any way?
Some e-mail programs will append a *.txt to the end of the *.lic file. If your license looks like 'license.lic.txt', then remove the *.txt extension. If you opened the file with Microsoft Word and then saved it as a *.doc file, it will not work either. The format must be ASCII.
Is your license intended specifically for your computer?
Make sure the hostID and/or registration ID in the license file matches your computer. You can see these IDs from STK's license manager. If you need to find your hostID independently, go to the DOS command prompt and type 'ipconfig /all' (for Windows 2000/XP/ and higher). The hostID is the number under 'Physical Address'.
Does your license include the basic STK module?
You may have a license for several STK modules but not the basic STK module. Open the license file and verify that the basic module called 'STK' is specified.
If you have a dongle license, did you load the dongle drivers?
The dongle requires a dongle driver that is available from the STK CD-ROM or please contact AGI Technical Support to obtain the driver for your version of STK.
If you have a network license, did you load the license server software?
Ensure the Flex license server matches your version of STK. The license server is available on the CD-ROM. Make sure the client and server licenses are not swapped in error.
Has your license expired?
Open the license and check the expiry date.
Is your license intended for your version of STK?
Open the license and check the version of STK. Go to the portion of the license that specifies the basic STK module. Ensure it matches the version of STK you are running. Note that a newer version license will enable an older version of STK.
Has your system clock changed recently?
If the system clock on your computer has moved back, STK's licensing software creates a warning in STK's message window and prevents STK from running. Contact AGI Technical Support for tips on resolving this problem.
